This podcast investigates the connection between a violent group called the Zizians and the Rationalist movement, a community of intellectuals focused on AI safety. The podcast details the Zizians' origins within the Rationalist community, their leader Ziz's increasingly erratic behavior, and the series of killings linked to the group, including the death of a border patrol agent and a landlord. Ziz faked her death and was eventually apprehended. The Rationalist community is now engaging in self-reflection regarding the events. The podcast highlights the unexpected consequences of open and inclusive communities and the resulting scrutiny faced by the Rationalist movement.
